How to convert PHP's crc32 hash into the MySQL equivalent?

Question

Apparently MySQL\'s CRC32() function returns an unsigned BIGINT, while PHP returns hexadecimal value.

In PHP:

hash(\'crc32\',\'hello world\') == 7813f744

Answer 1

If you have 64-bit platform you can safely use crc32 function in PHP and CRC32 in MySQL. Quick test:

  php > echo crc32('foobar') . "\n";
  2666930069

MySQL:

  >select crc32('foobar');
  +-----------------+
  | crc32('foobar') |
  +-----------------+
  |      2666930069 |
  +-----------------+
